What are the solution(s) to the quadratic equation 50 – x2 = 0? A. x = +2V5
B. x = +63
C. x = +5V2
D. no real solution
Please help hurry :/

±5 sqrt(2) =x

Step-by-step explanation:

50 – x^2 = 0

Add x^2 to each side

50 = x^2

Take the square root of each side

±sqrt(50) = sqrt(x^2)

±sqrt(25*2) = x

±sqrt(25)sqrt(2)=x

±5 sqrt(2) =x

If you have to choose an alternative, it is C. is one of the solutions/roots of the quadratic equation, but the correct answer is actually .

Step-by-step explanation:

Once

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
